High Data Volume Transfer Issues at NOAA Christopher D. Elvidge Earth Observation Group National Oceanic and Atmospheric Administration National Geophysical Data Center Boulder, Colorado August 26, 2005 chris.elvidge@noaa.gov
NOAA’s Vision and Mission • VISION – An informed society that uses a comprehensive understanding of the role of the oceans, coasts, and atmosphere in the global ecosystem to make the best social and economic decisions. • MISSION – To understand and predict changes in the Earth’s environment and conserve and manage coastal and marine resources to meet our Nation’s economic, social, and environmental needs.

NOAA’s Current Satellite Observing Systems • Polar-orbiting Operational Environmental Satellites (POES) ~10 GB per day. • Geostationary Operational Environmental Satellites (GOES) ~ 10 GB per day. • Defense Meteorological Satellite Program (DMSP) ~ 8 GB per day.
NOAA’s Future Satellite Observing Systems • NPOESS Preparatory Project (NPP) ~4 TB per day 2008- 2012. • National Polar-orbiting Operational Environmental Satellite System (NPOESS) C1 ~4 TB per day 2010-2015. • National Polar-orbiting Operational Environmental Satellite System (NPOESS) C2 ~4 TB per day 2012-2017. • National Polar-orbiting Operational Environmental Satellite System (NPOESS) C3 ~4 TB per day 2014-2019. • Geostationary Operational Environmental Satellites-R (GOES-R) ~ 2 TB per day 2012-2017.
The NOAA Comprehensive Large Array-data Stewardship System(CLASS) will be the long term archive for the data from these systems, providing data access for the scientific community.
Hardware and Network Design • CLASS will have three operational sites (NGDC, NCDC, and NASA IV&V) • CLASS will have a centralized development environment and a centralized integration and test environment at NSOF • CLASS will use a Multi-protocol Label Switching (MPLS)-based peerless IP network used for site to site communication • New hardware and network architecture • Implemented by January 2006 • Modular, scalable, and redundant • Addresses security requirements
NGDC will have direct access to the NLR via the Front Range GigaPop for use in delivering data from CLASS
The Data Hog? • The Visible-Infrared Imaging Radiometer Suite (VIIRS) will fly on NPP and each of the NPOESS satellites. • Raw data (RDRs) from a VIIRS will run 116 GB per day. • Radiance calibrated geolocated data (SDRs) will tilt to 815 GB per day. • Environmental data records (EDRs) will bulge towards 2 TB per day.
The Challenges • Moving the data within NOAA - from the Suitland to the CLASS nodes. • Providing simple, useable tools to establish and manage large volume data subscriptions. • Transferring large volumes of data to the users, including those in the APAN region. • MAFFIN, Chiba U., U. Tokyo, Tokoku U. in Japan have expressed interest in receiving global VIIRS data!
